Lemma 2.1 ([1]}) 
Let Assumption (A7) holds. Assume that functions
\(g_i(t), i\in \underline{m}\) , are almost periodic in the sense of Bohr,
a function \(\phi (t)\)  and sequences \(\lbrace \delta _k\rbrace \) , \(\lbrace \gamma _k\rbrace \) 
are almost periodic. Then for any \(\epsilon >0\) , there exist
\(\epsilon _1\in (0,\epsilon )\) , relatively
dense sets \(\Omega \subset \mathbb {R}\) , \(\mathcal {P}\subset \mathbb {Z}\)  such that
